ALV - how to make selectable only some rows on an ALV?

Hi my problem is:
I have an ALV GRID as output of a report.
I have to make selectable only few rows based on the contents of a field (showed in a column in the ALV).
Is it possible?
Best Regards, Vincenzo

I did understand, but as i told you there is nothing like that, neither an option nor an event to capture.
Here is the documentation: http://help.sap.com/saphelp_erp2005vp/helpdata/EN/bf/3bd1369f2d280ee10000009b38f889/frameset.htm

Select only some rows

Hi all,
I've a query with more than 500 rows as result. I'm only interested to show the first 50 rows. Did you know any way to prepare the select sentence to do it? I prefer avoid use cursors to do that.

hi
use ROWNUM keyword for fetching first 50 rows
simplest example
select * from emp
where rownum < 5 ;
regards
HiteshROWNUM applies to the rows after they are collected into a result set. Thus, it may, or may not, fulfill the OP's requirements. He still needs to define what he means by "first 5 rows".

Selecting only one row at a time

Hi experts,
i have following doubt regarding selecting rows from a db:
Is there any way of selecting only one row AT A TIME from a dabase just to collect the data in rows instead of in a unique document containing all the rows?
I would like you to ellaborate on this as i need to send only one row to the IE, and then other row, and so on... without throwing any error!
I have seen that there are SELECT SINGLE and SELECT UP TO 1 ROW, but these two methods are only useful when retrieving only one row, and that does not match my requirements. I need to process all the rows but one by one..
I know that we can use the receiver jdbc adapter as if it was a sender by means of its specific datatype, but how to do it row by row??
Hope i had explained well..
Thanks in advance and best regards,
David

Hi kiran,
Yes, my table has 5 not null fields but i am selecting and updating fixes values so i think that I will definetely go for the next solution:
SELECT * FROM t1 WHERE status='0' and ROWNUM<2;
UPDATE t1 SET status='1' WHERE status='0' and ROWNUM<2;
My only concern is if the update will take the same row that the select.... BTW, I think it will
..What do you guys think?
I ve been trying to operate with your proposed queries but i received some errors. Your queries are very interesting but i think that with the above ones i meet my requirements as the status field will be 0 for not processed rows and 1 for precessed ones (and the update will look for the row that meets the same 'where' clause than the select, and then, and only then, it will set status='1').
The only thing i have to care about is what i questioned before.
Thanks a lot and best regards,
David

From list of IAP's in Aruba Central, how do I select only a few of them for license assignment?

Q: I have hundreds of IAPs in the device management page of Aruba Central. How do I select only a few of the them to assign license?
A: Especially, when there is huge list of IAPs showing up in the device management page of Aruba Central, it becomes difficult and time consuming for an administrator to assign license for each IAP and then move on to the other.
This problem was sensed by the Aruba Central development team before hand and put up a solution in place that would help a user to select multiple IAPs from the list and assign licenses to them at once.
Lets understand on how to do the same:
1. Once you login to Aruba Central, click on "All Groups" and move on to 'Device Management" under Maintenance.
2. In the right-pane, you would be presented with the list of IAPs.
3. Now , click on the "Search tool" and it pulls down the fields to enter the search text.
(NOTE: Make sure you have selected ALL in the above drop down. This helps central to search among all IAPs irrespective of group and license assignment.)
4. Enter the Serial Number or MAC address of the IAP or Switch and hit "Search"
5. Here is where the intelligence of Aruba Central comes to play.
From the search result select the IAPs and Central would remember your selected IAPs, even if you change the search string and initiate an other search.
6. Once you finish searching all IAPs that you want to, you can click "Assign License" button in the lower left-corner and move on assigning the licenses to the selected IAPs

This was a life saver! I even started to manually tick the box as well!

I do not want all of the playlists in iTunes to be synced to my iPhone. With iCloud I do not seem to have a choice. How do I select only certain playlists for my iPone?

I have many songs and playlists in my iTunes account. I do not want all of them synced to my iPhone 5S, but that has happened via iCloud, and it has caused a storage problem on my phone. How do I select only certain playlists to be synced to my iPhone?

You need to start over with Music. On the iPhone Music screen uncheck sync music. Also, on the Summary screen uncheck "Manually manage music and videos", then sync and it should clear off your phone.
Next, choose the music you want to sync. If you want to fit more on check "Convert higher bit rate songs to 128 kbps AAC". This will reduce quality slightly, but it won't be noticable unless you are using $300 headphones.

How to print selection only

I saw this question on another forum and realized that I have no idea how to print 'selection only'. The only options in the file>print menu are for the pages desired. I see no way to print only the selected portion of a page. There must be a way, but I do not seem to be able to find the answer.
Thanks, Fran

I tried it with 'Grab' but the printout was too large. I then discovered that if you use 'Snag It' you can accomplish the same thing. Press Shift-command-3 for the whole screen or Shift-command-4 for a part of the screen. this creates a PNG image which when opened in 'Preview' can be printed. Rather complicated, but it does work. Thanks for steering me in the right direction.

How to make select list as read only

Hi All.
when i m loading a page ...how to make value of select list as read only ..
i tried doing this ....
i added readonly attribute to the select list's element attibute ...it is showing as read only field by darkening the select list field but ... the select list is editable even now... its allowing to choose from drag and drop ...
Thanks & Regard ,
Nandini

I have the same requirment..
I have a select list on a editable form and i want to make that one read only.
When I use read only property it doent do anything. (But this is working for text items well).
When I use "disabled' option it works fine. But then that value does not post when use POST the form. So making select list disabled is not a solution.
Any Idea..
Thanks

How to make a Jtable's row selected thru program

Hi , in my application few of the rows (not continous)
need to get selected automatically when the jTable is intially shown.
I did this using table.setRowSelectionInterval(0,2)
This method works fine selecting all the rows from 0 th to 2 th row,
but if i want only 0 th and 2 th ( excluding the 1 st row ) to be selected , i dont know how to do that???
i tried the following also
//indeces of rows to be selected in the table are stored
//in array
int[] array = new int [2];
parray [0]= 0;
parray [1]= 2;
table.setRowSelectionInterval(parray[0], parray[0] );
table.setRowSelectionInterval(parray[2], parray[2] );
//for each iteration a single row will be selected
//coz the starting and ending indeces are same ie
(parray[0],parray[0])
but when this code is run only the 2 nd row gets selected , what abt the 0'th row???
please help.
Thanx.

sorry
there is a small correction in the above code
//indeces of rows to be selected in the table are stored
//in parray
int[] parray = new int [2];
parray [0]= 0;
parray [1]= 2;
table.setRowSelectionInterval(parray[0], parray[0] );
table.setRowSelectionInterval(parray[1], parray[1] );
//for each iteration a single row will be selected
//coz the starting and ending indeces are same ie
(parray[0],parray[0])

Only some rows selectable

Hi,
I wonder if anybody could help me in my problem?
I made a table and would like only some of the rows to be selectable. Is this possible?
The best solution would be to hide those squares on the left of the rows.
Thanks in advance for your help.

Edited by: Piotr Kondratowicz on Feb 10, 2009 4:29 PM

Hi Piotr,
Create a value attribute of type boolean(Ex: ed) and assign it to all editable fields of the table.
Based on a condition enable(ed=true)/disable(ed=false) the row fields as read only.Which will fulfill your requirement.
Thanks & Regards,

How to make selected and active a child row of a treeTable?

Hello,
I am inserting a new child row into a af:treeTable, disclosing it, but I can't figure out how to make it selected and active so the focus of the user to go on it.
Jdeveloper version 11.1.2.3.0
This is how I am inserting the child node:
public void createLocation(RowIterator ri, Key selectedNodeKey) {
        final String locationCategoryViewDef = "model.views.LocationCategoryView";
        if (ri != null && selectedNodeKey != null) {
            Row[] found = ri.findByKey(selectedNodeKey, 1);
            if (found != null && found.length == 1) {
                Row foundRow = found[0];
                String nodeDefname = foundRow.getStructureDef().getDefFullName();
                RowSet parents = (RowSet)foundRow.getAttribute("LocationView");
                Row childrow = parents.createRow();
                //hardcoded locationId
                childrow.setAttribute("LocationId", 434558);
                parents.insertRow(childrow);
} And this is the treeTable:
<af:treeTable value="#{bindings.LocationCategoryView2.treeModel}" var="node" varStatus="vaarr"
              partialTriggers="gaga gag4a ga4a"
              selectionListener="#{bindings.LocationCategoryView2.treeModel.makeCurrent}"
              displayRow="selected" rowSelection="single" id="tt1" editingMode="clickToEdit"
              horizontalGridVisible="true" binding="#{pageFlowScope.treeTableBean.sampleTreeTable}">
    <f:facet name="nodeStamp">

    </f:facet>
    <f:facet name="pathStamp">
        <af:inputText value="#{node}" id="ot2"/>
    </f:facet>
    <af:column id="c2" headerText="Location CategoryName">

    </af:column>
    <af:column id="c6" headerText="Location CATID">
        <af:inputText value="#{node.LocationCategoryId}" inlineStyle="font-weight:900" id="ot6"/>
    </af:column>
    <af:column id="cgg2" headerText="Var INDEx">

    </af:column>
    <af:column id="c1" headerText="Location Name">
        <af:inputText value="#{node.LocationName}" id="ot3"/>
    </af:column>
    <af:column>
        <af:panelGroupLayout layout="vertical">
            <af:commandLink id="gaga" text="addLocation" inlineStyle="color:red"
                            action="#{pageFlowScope.treeTableBean.createChildren}"
                            rendered="#{node.LocationId == null}" partialSubmit="true"/>
            <af:commandLink id="gag4a" text="delete category" inlineStyle="color:blue"
                            partialSubmit="true" rendered="#{node.LocationId == null}"
                            action="#{pageFlowScope.treeTableBean.deleteChildRow}"/>
            <af:commandLink id="ga4a" text="delete location" inlineStyle="color:green"
                            partialSubmit="true" rendered="#{node.LocationId != null}"
                            action="#{pageFlowScope.treeTableBean.deleteChildRow}"/>
        </af:panelGroupLayout>
    </af:column>
</af:treeTable>

Yes I did now but nothing changes. The current, selected and active row is still the parent node...
Even I am adding AdfFacesContext.getCurrentInstance().addPartialTarget(this.sampleTreeTable); for just in case..

Same query canreturn rows in different order next time you run it unless you specify ORDER BY. Only ORDER BY guarantees order, so when you say first row/second row you must provide ordering criteria.

How to make a whole table row be read at once?

Hi,
I want to make a whole table row be read at once by screenreaders if the table is not editable?
I tried to use "getAccessibleSelection" and return a own implementation which returns the number of columns at "getAccessibleSelectionCount".
But if "getAccessibleSelectionCount" return anything else than 1, the method "getAccessibleSelection" is never called.
Does anybody have a idea or a suggestion to solve this problem?
Thanks in advance

Hi AJL,
If you mean a table of data values in the Data Portal, i.e. a list of channels, then yes you can do it. In that case you should just register load the channels you want to be read-only. You can do this interactively by right-clicking on the data file in question and select "Register data". You can also double-click on the file to select individual channels to load or register. Programmatically, this looks like
Call DataFileLoad(DataFilename, DataPluginName, ImportAction)
Setting ImportAction = "Register" will register load the channels. If dragging and dropping the data file loads it correctly, then you can set DataPluginName = "". Otherwise, you can specify there which DataPlugin to use for the import process.
You can also programmatically selectively load some of the channels from the data source:
Call DataFileLoadSel(DataFilename, FileImportFilter, ImportSelection, ImportAction)
The "ImportSelection" parameter works just like the CNo() function in DIAdem:
"GroupName/ChannelName"
"GroupName/[ChannelIndex]"
"[GroupIndex]/ChannelName"
"[GroupIndex]/[ChannelIndex]"
If, on the other hand, you mean a read-only table in the REPORT panel, your options are limited, though you can do that with a SUDialog.
